ArticCynda, Thanks for you kindly reply. That is really helpful to me.
Hi, arouse1973, the current source from the supply(60V) is modulated by 2KHz signal. so it is AC.
I have never laid out a PCB with potential higher than 24 volts, so I'm wary that must some "trivals & tricks" I will miss. so please give me your advice what should be paid attention when supply is 50v or 60v (and the current current may be 10A from the 60v supply.) for example special space...

Thanks, dick_freebird & FvM
but I want to know what is limited voltage range("But a current source
that only works right over a limited voltage range")

[help] can mosfet work in linear(triode) region in vccs(with op amp)?
HI,
I used the attached circuit to drive led about 10A. if mosfet operate in saturation region, the dissipation power of mosfet is large.
so is it possible that mosfet operate in triode region in vccs. and what is differences...
Hi betwixt,
Thanks for your replay, You means the output voltage will affect the selection of MOSFET, isn't it?, the circuit driver the gate through boost diode and capacitor. I want to know why the output should be less than 5.5V, the chip sense the output voltage through Pin Vsen.
1. I want to get an output 10V from ISL6227, though the datasheet says the output range is 0.9 to 5.5v? Is it possible while change the feedback divided voltage in VSEN pin?
2. The Maximum duty cycle of ISL6227 is 87%, and the phase shift is 180 between phase1 and phase2, If and when the duty...
